Restoring The Landscape With Native Plants Tall Beard Tongue Insect Visitors

Tall Beard Tongue ~ Penstemon digitalis
Beard tongue flowers have a large, hairy staminode on the lower half of the tubular flower which restricts access to bees to the flower and helps in pollen deposition. Small to medium sized bees are the most frequent visitors.

Tall Beard Tongue flowers can be white to light pink, sometimes with darker pink to purple stripes which act as nectar guides for bees.

Small Carpenter Bees (Ceratina spp) visit Tall Beard Tongue flowers primarily to feed on pollen. Their small size allows them to easily climb over the staminode into the tubular flowers to access the pollen on the anthers.

As they feed on pollen, they often inadvertently contact the stigma. The hairs on the staminode keep their bodies held closer to the stigma, resulting in more contact and pollen transfer.

Digger Bees (Anthophora spp.) are frequent visitors to Tall Beard Tongue flowers as well. They are fast moving and visit flowers for a very short time frame compared to Small Carpenter Bees.

Their medium sized bodies and long tongues allow them access into the tubular flower which results in abundant pollen removal as their bodies scrape on the anthers above.

Bumble Bees (Bombus spp.) are not primary pollinators of Tall Beard Tongue. Visiting the flowers for nectar, they are able to reach the nectar reward with their long tongues without having to insert their body into the corolla and come away with pollen on their bodies.

Look for small holes chewed at the base of the flower. Mason Wasps will chew holes to reach the nectar reward without having to enter the flower. Smaller bees will take advantage of these nectar thievery holes.

The Great Sunflower Project Article On The BUZZ: Join Us for the Great Bee Count on Saturday, August 11, 2012

The BUZZ: Join Us for the Great Bee Count on Saturday, August 11!

Greetings citizen scientists! Our poll results are in, and, at last count, some 46% of you have sunflowers up and blooming. About one-third (34%) are still waiting for blooms (or encountered an gardening mishap), and another 21% didn’t plant sunflowers this year.

Those of you lucky enough to have sunflowers in bloom are diligently sending in your bee observations. Congratulations to all those who have already had the opportunity to observe, collect and report their data. Well done! Without your thoughtful observations, we would not have the wealth of information that we have to date.

To see results from the project using data reported up to 2012, have a look here: http://www.greatsunflower.org/results#map – you can zoom in on your area, see averages by type of garden and trends by year. Great stuff, and all because of your participation!

It’s important that you keep sending in data, so please join us and thousands of others across the country in The Great Bee Count on Saturday, August 11th.

Even if you do not have blooms on your sunflowers by August 11th, you can still be enjoy, learn and be part of the project by observing bees on other plants that you may have in bloom. Cosmos, tickseed, bee balm and echinacea, are all on our list, so you can collect data on these if your sunflowers are not blooming yet. And, it’s okay if your sunflower hasn’t bloomed yet. They will in time so you can make your 15 minute observation when they do open up.

And, this year, in support of the Great Bee Count, YourGardenShow.com will present a special online live broadcast “Double Feature” on August 11th, from 10am – noon EST (7am to 9am PST). First hour: a special “Ask Ian” Q&A show about pollination and pollinators followed by an hour of moderated interviews with bee experts talking about our pollinator friends. Join us for this one day event!: http://www.yourgardenshow.com/ask-ian

As you can see from our map, bees are declining in certain areas, and there are some areas where we have no data. Could that be your garden? The more we know, the more action will be able to be taken to preserve and enhance pollinator habitat.

Join us on August 11th!
